Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, and the description's 'Read' is consistent with those. The description adds the detail of 'sanitized,' which hints that output is redacted, but it does not describe what health diagnostics are included or what error conditions might occur. No contradiction with annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, tightly worded sentence with no filler. It leads with the action and object, making it immediately scannable. It earns its place despite being terse, though its brevity contributes to the lack of parameter transparency.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a read-only health tool, annotations cover safety, but the description still leaves out critical invocation details. The `request_id` parameter is undocumented, there is no output schema to explain the response, and the description gives no sense of what 'health diagnostics' specifically contains. An agent cannot confidently call this tool correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema defines a single optional `request_id` parameter with no description, and schema_description_coverage is 0%. The tool description does not mention the parameter at all, so an agent cannot infer its meaning, format, or whether it should be supplied. The description fails to compensate for the lack of schema documentation.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a clear verb ('Read') and resource ('Workspace integration health diagnostics'), and the title reinforces the purpose. The word 'sanitized' adds a useful scope qualifier, and no close sibling tool overlaps with this purpose. It would be a 5 if it explicitly named a sibling alternative, but the absence of any similar tool makes it effectively distinct.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives, nor does it state prerequisites, workspace context, or when not to call it. The intended use is only implied by the name and title, which is insufficient for an agent deciding among a large set of tools.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
